It's a much cruder and half-baked version of a lot of other generic going to university and seducing girls games. You'll recognize all the classic tropes: from the mom who has a bunch of debt from the missing father, to the gyaru girl with the underpreforming jock BF you have to tutor, etc. Generic can be fine and even welcome if it's done well, but I don't really feel it is here.
For Story/Content: At release 9, it still feels like a alpha that I would say should've been left in the oven longer before release. There's a few early-in partial routes you can start with a few sprinkles of content, but for the most part a lot of it is warnings about "this isn't done yet, so do the other route", and it seems once you're on a route, you're ON that route with incredibly linear paths where choices don't matter. For example with the mom's debts, you can either offer to help pay or convince her to do 'modeling photos'. If you pick help, you get told this isn't in the game so pick the other option, so you pick the modeling then get a choice to either tell her how much she earned or lie to her, if you're honest then nada end of content and quest disappears, if you lie you're 0-60 forcing her to do a bikini shoot and openly jerking off on her ass. It's pretty crude nonsense that just forces you into the pimping route. Same with the gyaru where if you choose to actually tutor her, you're pretty much forced on the dominate her path even though it still gives you a buncha useless options not to which just do nothing until you pick the dominate one. Maybe I actually wanted to help her and break through the shell and do a romance path, not just start slapping her around.
I assume (hopefully) these will be fleshed out so the useless options actually do something for alternative flavors of routes in the future, but imo rushing forced routes like this with unfinished useless choices everywhere is a really poor way to develop a game. Nobody is gonna want to commit to a save where you have to make forced choices to obtain any content. Better to simultaneously develop paths, even if it's slower.
For Sandbox Elements: They aren't the most annoying I've ever seen, and it doesn't do room exploration thank god, but the time system is pretty meh. There's not enough activities to actually fill most days, so you definitely find yourself just skipping a lot just to reach the arbitrary day/time something happens.
As for Art: Renders are servicable, but nothing exceptional. Models are attractive girls but all have extreme proportions that look like unnatural Second Life sex dolls with organless pencil thin waists. Also does weird shit like erections coming out of the top of pants because I assume the dev doesn't have a proper tent morph for clothing. The one lewd scene I reached was pretty primitive with a very mid 1 second keyframed anim loop, and pretty short with about 5 lines of dialogue before it ended. If your visual posing skills are weak, you need to carry the scenes with good dialogue to make the situation hot, neither is really being done here.
Overall, mostly just a minefield of unfinished routes with characters that look like extreme Skyrim bodyslides. I'd probally recommend holding off on it to see if the dev can better flesh it out or not. It does have potential, it's just not nearly there yet.
